Description
AquaBlade – RC Water Jet Boat RS775 🚤
This project is a fully functional remote-controlled boat, nearly 50 cm long, powered by an RS775 water jet motor. Control is via a DualShock gamepad using a transmitter on ESP32 and a receiver on Arduino Nano.
The boat includes:
- RS775 motor with BTS7960 driver ⚡
- MG90S servo for the rudder 🛶
- Metal shaft and 5 mm coupler 🛠️
- nRF24L01 for wireless communication 📡
- 3S LiPo battery 🔋
The transmitter uses:
- ESP32 💻
- 18650 battery 🔋
- nRF24L01 📡
- DualShock gamepad 🎮
This project demonstrates wireless boat control with LED feedback for motor speed modes and servo-based rudder steering.
